It's interesting to me that Okunari would mention N.Y as doing music for HOT ROD,
as Hiro's Hitmaker profile lists the game with the clarification BGM一式, which I assume would mean All BGM, though I could be wrong (or even Hiro could be wrong).
For reference, the other games he clarifies BGM一式 with are PIT POT, MAGIC HOUSE and Rail Chase: The Ride.
